Application filed m 4,

This invention relates to a loom for weaving reed, fibre, and other similar material still material as filling or weft in a fabric,

without the use of a shuttle or carrier for the filling.

A further object is to provide a loom in which reed or similar filling may be alternately fed from both sides of the loom, thus greatly increasing the output of the loom.

An important feature of my invention relates to the provision of an improved and simplified driving mechanism by the use of which the usual harness cam shaft may be omitted.

My invention further relates to arrangementsand combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings in which- Fig. 1 is aside elevation of the loom embodying my improvements;

Fig. 2 is a front elevation thereof;

Fig. 3 is an enlarged side elevation of the lay and certain parts associated therewith;

Fig. i is an enlarged side elevation of the harness actuating mechanism; 7 v

Fig. 5'is a detail front elevation of a por tion of the lay;

Fig. 6 is a side elevation of mechanism tor cutting the filling;

Fig. 7 shows a modified arrangement of driving mechanism, and Fig. 8 shows another slight modification. Referring to the drawings, my improved loom comprises the usual frame having loom sides 10 and 11 and cross girts 12 and 13. -Two or more harnesses 14 may be supported in any usual manner, as by straps 15 and pulleys 16, on a harness shaft 17 rotatably mounted at the top ofthe loom sideslO and 11.

'lhe warp threads W are supplied from the usual warp beam rotatably mounted at g the back of the loom and provided th the usual let-o1? mechanism (not shown), The

' woven fabric may be, z;uidedv around a roll.

20 at the front of -the-loom and may be wound on a roll 21 intermittently rotated by shown) 1923. Serial m'. 636,652 I The harnesses may be'iactuated in any convenient manner but I have shown herein a desirable construction by which harnesses of any desired width may be easily operated. For this purpose I provide one or more plnions 22 on the harness shaft 17 these pinions being engaged by vertically movable rack bars 23 each having a pin and slot connection at its lower end to a bent lever 24, mounted on a stud 24* and having an elongated cam follower 25 pivoted thereon.

The cam follower 25 is positioned in the double groove 26 of a cam 27 which is preferably fixed direct to the main driving shaft 28 of the loom. The follower 25 has a groove 29 in its outer face and the cam 27 has a plurality of pins or studs 30 mounted as indicated at the intersection of the inner and outer grooves of the cam. With this construction, the cam follower 25 will shift alternately between the inner and the outer grooves, thus producing a two-revolution effect from a single revolution cam and avoiding the necessity of providing the usual harness cam shaft operated at one half the relation by screws 37. The plates 36 are of substantial width and form the equivalent of the reed or comb commonly used in Weaving. The plates hold the warp threads W in properly spaced relation and also serve to beat up or press the filling into place in,.,

the fabric as the shed is changed. 7 A rail or cross bar 38 is mountedon loom frame and extends across the loom above the lay 31and plates 36. This bar QS- supports a seriesJof upper plates 39;each

directions and it will be evident that it rehaving a stud 40 which extends through a slot 41 in the upper end ofa guide arm-A2: Each 'ide arm is pivoted. at 43;.to the upper;-

end 0 a plate 36, the arms corresponding to'the plates in number and transverse position. Each guide arm is notched or recessed at 44 On its rear face and the ends of each recess are preferably beveled or countersunk to facilltate the entrance of a reed into the recess.

When the lay is in its rearward position,

the shed is open and the guide arms 42 are in the position shown in full lines in Figs. 1 and 3. Forward movement of the lay causes the arms 42 to swing forward and upward to the position shown in dotted lines in Fig. 3, the lower ends of the arms being then above the warp I and permitting the inserted filling to be beaten into the. fabrics.

The slots 41 may be long enough to per mit any desired forward movement and the rapidity of the swinging movement of the arm is determined by the angular position of the slots. The provision of separate plates 36 and 39 greatly facilitates repairs and replacement in case of accident to one guided by the rolls 50 to the recess 44 of the of the arms 42. Obviously, the notches or recesses 44 may beformed in the plates 36 instead of in the arms 42", as indicated in Fig. 8-.

For feeding the filling, I provide a pair ofv feed rolls 50 at one side of the loom and a guide tube 51 which facilitates the presentation of the pieces of reed or other. filling to the rolls 50. The filling is suitably first guide 'arm 42, the arm being then in operative position adjacent the correspond:

ing plate 36 which closes the back side of the recess. As the reed is advanced by the rolls 50, it is guided by the successive openings or recesses 44 and is thus inserted in the open shed of the warp threads W. When weaving with reed, the reed is commonly provided in lengths substantially corresponding to the width of the fabric.

Any convenient driving mechanism may 7 be provided for intermittently rotating the feed rolls 50. In the drawings, I have shown I an intermediate shaft 52 connected by bevel gears 53 and 54 to a shaft on which the lower feed roll 50 is mounted, the upper and lower rolls being connected by a pair of gears 55. At its lower end, the shaft 52 has a friction roll '56 engaging a disc ,5?- on 'a shaft 58 geared to rotate in unison with the driving shaft 28. The disc 57 has its driving surface cut away so'that the friction roll .56 is en.-. gaged and rotated during a portion only of each revolution of the shaft 58, the partsbeing timed so that the rolls 50 are actuated and the reed or other material is-inserted while the lay is in its rearward position and de arms 42 arein raised position.

he f e r ll nd their-driving mechanism are preferably duplicated at thetopposite side of the loom, so that filling or-weft mayi be fed to the loom from either side, or alter; nately,.firs t from'ene sldeandtheafrem the e 'T shaft 58'extends across the loom andother. The latter arrangement is very desirable when using reed, as it is necessary to present each separate reed manually to the guide tube 51 and rolls 50 and the speed of operation of the loom is limited to the number of reeds which can thus be presented. By alternately feedingthe reeds from opposite sides, the production of the loom is substantially doubled.

As shown in the drawings, each pair of rolls will be actuated at each revolution of the driving shaft 28 and of the feedshaft 58.

It is obvious that by a slight change in the ratio of the gearing and in the relative setting of the discs 57, the shaft 58 may be caused to rotate one half as fast as the shaft 28 and each pair of feed rolls may be given a feeding movement once. for each two revolutionsof the shaft 28. An arrangement by which this'may-be accomplished is indicated in Fig. 7.

Having described the construction of my most position, the reed being guided through the recesses formed between the arms 42 and the plates 36. The shed opening'and harness air of warp threads is placedmotion is-much less than in the usual loom, 4

as no shuttle or other weft carrier passes through the shed. As soon as thereed is fully inserted, the lay moves forward tobeat up the inserted reedand the arms 42 are simultaneously swung upward out of the.

path of the advancing reed. The harnesses are simultaneously shifted and the lay in the new shed.

This second reed may desirably be inserted from the opposite side of the loom, during which feeding operation the first operator is resenting another reed to the feed rolls 50.

- n this way each operator is required to feed only once for each two beats of the lay "and to greatly increase production.

When weaving reeds, the reed is commonlycut in len only slightly; greater than width of e fabric bu hen weaving fibre.

or other continuous rial whichis suppliedfrom ls ,er convenient storfromio ne side .rells' operating stenchchangeof the shed. It is awry in using cont nuous fibre time loom, thefeed moves back for the insertion of another reed the" l the loom can be correspondingl speeded up to provide means for cutting the fibre after eac a fixed knife 60 and a movable knife .61.

mounted on a bent lever 62 having a roll 63 engaging a cam 64 on theshaft 58. At each revolution of the shaft 58, the knife 61 descends to sever the fibre just before the lay moves forward. M improved. loom is thus equally well adapt for operating upon continuous fibre or upon reed which is supplied in separate pieces.
